Invalidity of Successive Reassessments Without Fresh Material: An In-Depth Analysis of ITAT Mumbai's Ruling

The fundamental principles of tax jurisprudence dictate that an assessing authority cannot repeatedly scrutinize a taxpayer's records based on the same set of facts. This principle was recently upheld by the Mumbai Bench of the Income Tax Appellate Tribunal (ITAT) in the landmark case of Vaibhav Dwarkanath Warekar Vs ITO. The Tribunal decisively quashed a subsequent reassessment action, ruling that initiating a second review without the introduction of fresh, tangible evidence is legally unsustainable. Such an action merely represents a "change of opinion," which is strictly prohibited under the provisions of the Income Tax Act, 1961.

The dispute centered around the repeated reopening of the assessee's financial records for A.Y. 2009-10. The core legal question was whether the assessing officer possessed the jurisdictional authority to trigger Section 147 and Section 148 of the Income Tax Act, 1961 multiple times for estimating income on identical turnover parameters.

Chronological Factual Matrix

The Original Assessment and First Reopening

The assessee, who operates a trading enterprise dealing in forged steel materials, submitted the initial return of income for A.Y. 2009-10 on 29.09.2009. The declared income in this return stood at Rs. 5,62,780. The tax department initially processed this filing under the framework of Section 143(3).

Subsequently, the department received intelligence from the Sales Tax authorities suggesting that the assessee was a beneficiary of fabricated billing networks. Acting on this intelligence, the tax department initiated the first round of reassessment by issuing a notice under Section 148 on 17.03.2014.

During this first reassessment, the adjudicating officer finalized the order on 16.03.2015, rejecting the book results and estimating the business income at 0.50% of the sales turnover. This estimation resulted in an upward revision of the income by Rs. 18,95,029.
